Suspension wire for hanging optical cables

Suspension wires and clamps provide secure, vibration-resistant support for optical cables, ensuring minimal stress and safe installation over spans.

Types of Suspension Systems

Mechanical Suspensions: Lightweight mechanical suspension systems are designed to support optical ground wire (OPGW) cables across various line angles and spans. They handle vertical, transverse, and longitudinal loads without damaging the cable strands or affecting optical fiber performance. Breakaway bolts simplify installation and eliminate the need for specialized torque tools, making them cost-effective and reliable for long spans.

Fiber Suspension Clamps: These clamps are specifically designed for overhead optical cables. They distribute static stress evenly, improve vibration resistance, and prevent bending stress that could cause optical loss. High-quality aluminum alloy construction and flexible rubber clamp blocks enhance durability, self-damping, and corrosion resistance.

They are maintenance-free and suitable for a range of cable diameters and spans. Wire Suspension Kits: For indoor or commercial applications, wire suspension kits allow optical cables, lighting, or other equipment to be hung from ceilings or structures. These kits include ceiling brackets, wire ropes, and cable grippers, offering adjustable height and secure support.

They are versatile for trade fairs, interior fittings, or industrial installations.

Key Components

Suspension Wire/

Rope: Provides the main support for the cable, available in single, duplex, or multi-cable configurations. Clamps and Grippers: Secure the cable to the suspension wire while minimizing stress and vibration. Breakaway Bolts: Ensure proper torque during installation without specialized tools.

Vibration Dampers: Reduce fatigue caused by wind or environmental vibrations, especially for outdoor OPGW lines.

Installation Considerations

Cable Diameter and Span: Select suspension clamps and wires according to the cable's outer diameter and the span length to prevent excessive bending or stress. Load Distribution: Ensure clamps provide uniform stress distribution to protect optical fibers. Environmental Resistance: Use corrosion-resistant materials like aluminum alloys for outdoor installations.

Dynamic Loads: For outdoor cables, consider wind-induced vibration and angle changes; mechanical suspensions and vibration dampers help mitigate these effects.

Applications

Overhead Transmission Lines: OPGW and ADSS cables on towers or poles. Indoor Installations: Suspended optical cables in commercial or industrial buildings. Specialized Installations: Trade fairs, acoustic systems, or lighting integrated with optical cable runs.

Using the appropriate suspension wire system ensures safe, durable, and low-maintenance support for optical cables, protecting fiber integrity and maintaining optimal transmission performance.
